The hamburger you put on the grill this weekend could be from cattle raised on feed that includes chicken feces. Lester Graham reports…a year-old Food and Drug Administration rule says it’s safe.
The rule came about after the mad cow disease outbreak. It made some changes, but still allows putting chicken litter – that’s the straw, feathers, chicken manure and scattered food left after raising chickens in a building– into cattle feed.
David Kirby wrote a book entitled “Animal Factory.” He says the government buckled to the chicken industry because the industry didn’t have a place to go with all the chicken litter.
“There’s too much to spread on local farmland, so they very often put it into cattle feed. It contains urea which cows can convert into protein.”
Chickens are messy. They scatter their feed and it gets into the chicken litter that’s put in some cattle feed. Some chicken feed contains beef by-products. Kirby says cattle eating cattle by-product could risk another outbreak of mad cow disease. The FDA says there’s no measurable risk.

The future of an insecticide used on food is on trial. The Environmental Protection Agency wants to stop the use of the chemical. Rebecca Williams reports the pesticide company and some growers’ trade groups have been fighting the EPA:
For four years, the EPA has been trying to stop the use of the insecticide carbofuran.
The EPA says there are a couple problems. First, it’s toxic to birds. Second, the agency says carbofuran residues on food are not safe for us.
FMC Corporation makes the chemical. It’s been fighting the EPA for years. Now it’s before a U-S appeals court.
Corn, sunflower and potato farmers say they need carbofuran.
John Keeling is the CEO of the National Potato Council.
“Would there be potato production next year in the U.S. without carbofuran? Absolutely. Will it make decisions much more difficult for a lot of growers? Yes.”
The trial for the use of the insecticide is expected to last for months.

A new study finds people are
surprised to learn how much of their
exposure to chemicals comes from the
things they buy. Rebecca Williams reports:
In this study, researchers showed women the results of tests done in their
homes. The researchers sampled dust and they also measured chemicals in the
women’s bodies. On average, they found about 20 different chemicals.
Rebecca Gasior-Altman is the lead author of the study in the Journal of Health
& Social Behavior.
“Participants were surprised about where these chemicals were coming from
and did not anticipate that they were likely coming from products they brought
into their homes every day and used on their bodies unknowingly and were not
from big industrial dumps.”
She says, before, the women had thought of pollution coming from big
environmental disasters, and not daily exposure to chemicals from carpeting,
furniture, cosmetics and other things we buy.

News about dangerous chemicals in toys,
cosmetics and cleaning products has a lot of
Americans spending extra money. People want to
make sure they’re choosing things that are safe
for their families. Julie Grant reports that
other countries are ahead of the US in efforts
to improve the safety of all products:
So you might expect that the government has tested those
chemicals to make sure they’re safe. But you’d be wrong.
Daryl Ditz is senior policy advisor at the Center for
International Environmental Law.
He says the US Environmental Protection Agency has never
assessed the hazards of most chemicals used in every day
products.
“That means the EPA doesn’t know, and you and I don’t know,
which materials on the shelves are more dangerous and
which are less.”
Ditz says only a few hundred chemicals have been
thoroughly tested by the U.S. government, but there are
80,000 chemicals used in products on the market.
In the U.S., the EPA has to prove a chemical is harmful to
keep it off the market.
(sound of toy store)
Dorothy Bryan is shopping at this upscale toy store in Northeast Ohio.
She’s got three grandkids. She’s looking at an
organic cotton bunny, colorful wooden blocks, and of course
Thomas the Tank Engine. She
pays more for toys at this store than she would at the big box
retailer. But Bryan says they’re worth it.
“They’re not toxic. That’s the big part. They’re not the
plastic toxic things.
I purchase usually the wooden toys. The little one puts
everything in his mouth.”
But most kids’ toys are made of plastic. And lots of plastics are made with phthalates. It makes them pliable.
But phthalates are endocrine disruptors. They’re gender-bender chemicals that make girls develop earlier and reduce testosterone levels in boys.
That’s why
California has banned the use some phthalates in toys. So
have Japan and the European Union.
But Daryl Ditz, chemical expert at Center for International
Environmental Law, says regulators in the U.S. don’t have
much power to ban phthalates or other chemicals.
Chemicals here are innocent until proven guilty.
“That is, companies can sell virtually anything in a product or in a barrel unless it’s been proven
to be dangerous.”
But other countries are starting to take the opposite
approach. Ditz says the European Union is rolling out a new
set of laws that make chemicals guilty until proven
innocent.
“They’re putting the responsibility squarely on the shoulders
of the chemical makers. As opposed to having the
environmental authorities look for a needle in the haystack,
they’re saying, ‘this should be the responsibility of the
companies who make these materials.’”
Under the EU law, manufacturers will have to study and
report the risks posed by each chemical: whether they
cause cancer, birth defects, or environmental problems.
The Bush administration and chemical manufacturers tried to
block the European law. But they couldn’t.
Ditz says leaders in the
chemical makers’ trade group are now running around like
their hair is on fire. They’re worried – the costs to comply
could be in the tens of millions of dollars for some
companies that export chemicals to Europe.
But many individual companies have already started to
comply with the law.
Walter van het Hoff is spokesperson for Dow Chemical in
Europe. He says cataloging Dow’s 7000 chemicals is a
huge effort, but they don’t have a choice.
“You need to comply; otherwise you cannot sell them
anymore in the European Union.”
There are a half billion consumers in the EU and Dow wants to keep them. Dow and other
manufacturers might have to reformulate – or even abandon
some chemicals if the EU decides they’re unsafe.
While the U.S. is not considering a comprehensive chemical
review like Europe’s new laws, about 30 states are
considering new regulations on chemicals in toys. The Toy
Industry Association doesn’t want a patchwork of laws, so
it’s called for national toy safety standards.

There are few things as aggravating as getting stuck in a traffic jam. But for some drivers crossing a busy bridge from the U.S. to Canada there’s aggravation on top of aggravation. Joyce Kryszak reports that’s because a plan to build an additional bridge is being blocked by concern for a bird and a little fish that it eats.
Every year, millions of people cross the mighty Niagara River on the Peace Bridge that connects Buffalo, New York to Canada. And many of them sit for hours in a traffic jam. The border crossing and passport checks slow things down. But there are just not enough lanes for all the traffic.
Ice delivery man Tim Holliday is one of those who is fed up with hours and hours of bridge delays.
“Like, I gotta go to the duty-free here, and when I’m coming out of here I have to go through customs and they always ask, what were you doing in Canada?” said Holliday. “I’m just sick of the hassles, you know?”
Transportation officials say a new bridge is needed. The traffic problems will only get worse. Because of increased trade, about eleven million additional travelers are expected to be using the Peace Bridge over the next decade.
And that’s a headache for Ron Rienas. He manages the busy international bridge crossing. He says building a new bridge would help with the traffic delays and help with national security.
“This is a border improvement project designed to address redundancy issues, security issues, traffic flow, all of those things, maintenance issues…all of those are impacted by not being able to proceed with the project,” said Rienas.
A second bridge has been designed. It’s a cable-stayed bridge with towers as high as the Washington monument.
Brian Higgins is Congressman for the area. He’s pushing for federal approval of the impressive cable design. He says the region needs an iconic symbol of progress.
“We are in the eleventh hour of a project that’s been going on for fifteen years. We need additional capacity at the Peace Bridge to promote the efficient, predictable flow of commerce between the United States and Canada – we need an iconic bridge, a signature bridge,” said Higgins.
But that signature bridge is exactly the kind of design that is dangerous to many birds.
And the Niagara River is a virtual highway for nearly three hundred kinds of birds. The cables can be invisible to the birds and they can fly into them and die.
Among those birds is the Common Tern. It’s an endgangered species.
Terry Yonker knows these and other birds better than most.
“We probably documented somewhere in the range of half a million birds, and there’s a common tern right there.”
Yonker is a scientist and a former Ornithological Society president. He wrote an environmental study that recommended against the bridge’s cable design because it could kill hundreds of different kinds of birds, including the endangered tern.
Yonker says even if it avoided hitting the cables by flying over the bridge, the tern would be stressed by such a tall bridge design. That’s because it has to make eight trips over the bridge each day to feed its young. But he says it probably wouldn’t make that many trips if the new bridge is any higher than the Peace Bridge.
“You raise that structure and they’ll have to spend a lot of energy doing that. They’ll maybe make five or six trips a day and that means one or two chicks are going to get less food out there,” said Yonker.
The other concern is a food source for the tern.
Fishery experts say the enormous piers would change water currents, eventually killing off the Emerald Shiner. That’s the tiny fish the endangered bird feeds on.
So a new design is being recommended: A lower bridge with smaller piers to protect the tern and the emerald shiner.
Federal and state agencies are working to find a way to mitigate the threat to the birds and fish by altering the plans for the new bridge. But environmental experts say you can’t mitigate extinction.
Environmentalists and some biologists say the common tern is more than an endangered bird. They say it’s a warning, about what happens when sound science is ignored for the sake of progress.
But, try explaining that to the people stuck in traffic for hours because a second bridge is being blocked to save a small bird and a little fish.

Just when you thought polar bears in the United States were safe under the Endangered Species Act… they’re facing a new threat. The Bush Administration has announced regulations that allow oil companies to harass polar bears while they explore for oil off the coast of Alaska. Richie Duchon has more:
Oil companies can’t kill polar bears. That still brings a penalty. But they are legally protected from any accidental harm caused by trucks, boats and experiments that alter the polar bear’s environment.
The U.S. Fish and Wildlife Service’s Bruce Woods says oil exploration is not much to worry about.
“Believe me, you won’t find more concern for the polar bear anywhere than you will in this office, but we just don’t really believe that this activity at this level poses any significant threat. The threat to the polar bear is the loss of sea ice.”
Environmental groups are furious. They say the loss of sea ice from global warming is a threat to the polar bear, but they say we need to minimize other threats with a moratorium on oil exploration.

Frogs are in trouble. A nasty disease caused by a fungus is wiping out frogs around the world. But researchers might have found a solution. Rebecca Williams has more:
A disease caused by something called chytrid fungus is sweeping through frogs. When the disease moves through a frog population it can wipe out 80% of the entire population. Scientists have been rushing to find something that might help.
Reid Harris is a biologist at James Madison University. He says he’s discovered there are friendly bacteria that live on some types of frogs. And they can kill the fungus.
“It does seem like the pathogen moves in this predictable wave, so you might be able to get out in front of that wave sort of like a fire line.”
Harris says it might be possible to give wild frogs extra doses of the bacteria to fight off the fungus. But first they have to make sure there won’t be side effects.

Recently there’s been a big concern about bisphenol-A, or BPA, in some plastics. Some plastic baby bottles
and some water bottles have been pulled from the shelf by retailers. Grist is an online environmental news
outlet. The journalists at Grist have been looking at the BPA issue for a few years. We got a chance to talk
with Sarah Burkhalter at Grist about BPA and why it’s suddenly in the news:
Sarah Burkhalter: “BPA has been in our bottles for a long time, and there have just been some
more high-profile studies in the last year. Back in February 2007, the National Institutes of Health
came out with a report saying that there was a link to BPA and health problems. Even at that point,
people were switching over to glass baby bottles and things like that. But just in the same week,
there was another National Institutes of Health high-profile report, just a few days separate from
when Health Canada – the Canadian Health Department – also expressed concern. So, I just think
it was in the news, and people are suddenly realizing that this is a problem.”
Lester Graham: “So, it was a one-two hit in the media, plus when you mention baby bottles, or
possibly the liners of formula cans, that gets people a little nervous, if there’s something toxic in
that stuff.”
Burkhalter: “Absolutely. And, the thing with BPA is that it’s an endocrine disrupter, it can mimic
estrogen. And so the plastics industry has been saying, ‘well, we use it in such small amounts, no,
it’s no problem’. Other studies have said that even in very, very small amounts, BPA can sneak in
and change cell structure, and really muck-up the reproductive system. And it’s been linked to
early puberty, and breast cancer, and behavioral disorders, and all kinds of things. So when they
hear about this being in, you know, things that we’re regularly eating and drinking from, they pay
attention.”
Graham: “Now, here’s the big question – we’ve seen retailers pull some bottles off of the shelves,
there’s been this controversy with Nalgene, and now even a lawsuit against Nalgene about their
plastic bottles – what plastic bottles are safe to use, what ones can’t I use, how do I tell the
difference?”
Burkhalter: “well, BPA is found in number 7 plastic – that’s also known as polycarbonate or lexan –
and that’s the clear, hard plastic. So Nalgene bottles – not the white ones – but the brightly
colored, clear ones. Those are number 7. There’s also, as you mentioned, plastic adhesive in
linings of cans, some of those, BPA is also in some dental sealants. But when it comes to bottles,
number 7 is the one you want to watch out for when we’re talking about BPA. Number 3 has its
own problems – that’s PVC or vinyl – that’s another one you want to watch out for. If you gotta use
plastic, you’re gonna want to look for numbers 2, 4, and 5.”
Graham: “So we look for those numbers on the bottom of the bottle?”
Burkhalter: “Yup. Those are, I mean, you know, they’re not on every plastic, but if there is a
number on them, its ‘2, 4, and 5 to stay alive’. It’s the rhyme I just made up.”

The investigative arm of Congress says the
government is taking too long to review safety data
on chemicals. Rebecca Williams reports:
The Government Accountability Office says it’s taking the Environmental
Protection Agency too long to determine the safety of chemicals. The GAO
says reviews of chemicals should only take about 2 years. But some have
taken 10 years or longer.
The GAO also says a recent change could corrupt the system.
That change allows other federal agencies to make comments about chemicals,
but keep those comments hidden from public view.
John Stephenson is with the GAO. He says that threatens the system’s
integrity.
“There are just too many opportunities for non-scientists to intervene in
this scientific process and the result of that is it’s stretched out the
process for a given risk assessment.”
And a recent survey of EPA scientists found that political pressure from the
White House has been more common under the Bush Administration.
Apple grower Jim Koan has discovered that baby pigs are best for taking care
of fallen wormy apples in his orchard. He says they have very tender noses.

There are a lot of insects that love to eat
apples. A harmful insecticide that kills some of
those pests is being phased out. So farmers are
looking for other solutions. Rebecca Williams visits
an apple grower who’s counting on pigs to get some
help with his pest problem:
(farm animal sounds – turkeys, etc)
The spring rains have started, and at Jim Koan’s pig pen that means mud.
(sound of shoes squishing in mud and piggy snorts)
Of course, these pigs don’t really seem to mind that.
“These Berkshires, you can see, are really friendly, they’re just coming
right up to you.”
Jim Koan really likes his pigs. That’s because he’s hoping the pigs will
take care of one of his worst pests. It’s a beetle called the plum
curculio. In early spring the beetles lay eggs in the little green apples.
The larvae hatch and eat the apples from the inside out.
Then the tree drops the bad wormy apples on the ground. And the worms just
keep on eating.
For a long time, farmers used an insecticide called azinphos-methyl to kill
the beetles. But the Environmental Protection Agency is phasing it out.
That’s because the EPA says the pesticide is very toxic to some wildlife and
it can make farm workers sick.
Jim Koan hasn’t used the pesticide for 10 years, ever since he became an
organic grower. So for years now he’s been trying to find a perfect
predator to stop the beetle larvae.
The chickens were too lazy. Hawks ate the guinea fowl that he tried.
So, finally, Koan says he had a flashback. His grandpa used to have hogs in
the orchard.
“When I would climb up to go up in the tree in the summertime to get a green
apple to eat all the hogs would come running over there and my granddad
always told me you stay away from those hogs they’ll eat you up! I’d be
really scared and be up there for an hour or two until the hogs left again.”
(laughs)
Koan says he knows now that the hogs were just hoping for a snack. So last
year he decided to buy some hogs and see if they would eat the wormy apples
on the ground. He says baby pigs worked best.
“And they’d just go up one row gleaning it, kinda like little vacuum
cleaners (makes sucking sound) and suck up all the apples!”
Koan says the baby pigs ate 98% of the fallen apples with beetle
larvae in them. But he still needed to know that the beetles were actually
gone, so they wouldn’t come back to attack his apples next year.
That job
was up to researchers at Michigan State University. Koan says they fed a
mix of beetle larvae and apples to pigs on campus.
“Then they put diapers on the hogs – truly, diapers!! It was unbelievable.
They took special superglue and velcroed it on their butt so then when they
defecated they caught all that. Then they took these poor students and made
them go through there and wash all that and look for worms.”
Koan says out of 200 worms that were fed to the pigs, they only found one
worm at the other end. That means, so far it looks like pigs are a
pretty good predator.
But the researchers don’t want to let pigs run wild – just yet. David
Epstein is the lead researcher on the project.
“Jim and I are scheming all the time. I have great expectations that this
could be a good management tool in the future but we have to figure out how
to do it properly.”
Epstein says they need to make sure the pigs don’t cause any contamination
problems. Something like E. coli. He says so far there isn’t any
evidence of that, but it’s the kind of thing you have to be sure about.
If this all goes well, the farmer and the scientist will be writing a book
together. It’ll be sort of a self-help book: getting pigs to take care of
what’s bugging you.
